Final answer:
To determine the most you can pay for the antique pitcher, you need to find the original cost and add a 37% markup. Assuming the cost of the pitcher is C dollars, the maximum you can pay is $15.34.
Step-by-step explanation:
To determine the most you can pay for the antique pitcher, you need to find the original cost and add the desired markup. Let's assume the cost of the pitcher is C dollars.
The markup would be 37% of C, which is 0.37C.
The selling price should not exceed $21, so we can set up the following equation: C + 0.37C ≤ 21.
Simplifying, we get: 1.37C ≤ 21. Divide both sides by 1.37 to solve for C: C ≤ 15.33.
Therefore, the most you can pay for the pitcher is $15.33 rounded to the nearest cent, which is $15.34.
